### Please describe the problem.

After an update the webapp won´t start. git-annex itself works just fine :)
It doesn´t even try to open the browser. It seems like the command isn't recognised.
(Invalid argument `webapp')

### What steps will reproduce the problem?

git annex webapp


### What version of git-annex are you using? On what operating system?

I just updated to version 10.20220822 via homebrew on MacOS 12.5.1 (Monterey)

### Please provide any additional information below.

[[!format sh """
# If you can, paste a complete transcript of the problem occurring here.
# If the problem is with the git-annex assistant, paste in .git/annex/daemon.log

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
I had tons of luck using git-annex. I am a non-programmer person and I could easily get the hang of it. At the moment I am using it for my podcast production.
I can cut and export now from every available computer in my home. I have a central server on my LAN and git-annex also helps me to back up every episode.
My next goal is to use it for my personal documents like scans of invoices, letter and so on. I think an archive repo will help me with this. So I can have all the stuff in one big folder.
Thanks for inventing such a nice tool
